Prioritize carrier connectivity and transit times to your customer base, WMS and API integration, visibility and reporting, SLA terms, scalability of space and labor, and the provider’s service mix (kitting, returns, temperature control). Also validate local labor availability and contingency planning for peak seasons.

Get detailed modeled quotes for your SKU profile and volume tiers that include storage, pick/pack, handling, and zone-based last-mile rates. Compare cost-per-order, inventory carrying costs, potential multi-node savings, and expected transit-time improvements to quantify net savings.

Require WMS with real-time inventory sync, robust APIs or EDI for order and fulfillment flows, carrier tendering integration, exception alerts, and standard SLA reporting. Validate sandbox integrations, data formats, and the provider’s ability to support order orchestration and batch processing.

Assess SLA penalties, insurance and liability terms, security and temperature-control capabilities, contingency plans for labor shortages, scalability during peak demand, and clarity on inventory ownership and dispute resolution to reduce operational exposure.
